Addressable Fire Alarms
Modules and Pull Stations
E-Series
Edwards Signaling pull stations are addressable
modules designed for use in small buildings, and
are uniquely identified on the system by means of
rotary switches. Once registered, they share data
and update status information that determines
how the system behaves and how connected
devices interact with one another.
Each E-Series device contains a microprocessor
to distribute intelligence throughout the system so
that command decisions are made instantly at the
individual module, rather than at the control panel.
This feature helps to speed event processing.
